任务1-2:区块链系统部署与运维

通过给定区块链项目需求,进行区块链系统部署,包括系统部署、控制台部署等。通过监控工具完成对网络、节点服务的监控。最终利用业务需求规范,完成系统日志、网络参数、节点服务等系统结构的维护。

  1. 部署区块链服务器,配置管理平台参数及访问端口;
  2. 部署项目节点,获取管理平台与节点服务的加密通信;
  3. 部署应用程序接口服务,应用工具完成接口部署;
  4. 部署区块链系统,对接应用服务器和数据库。

子任务1-2-1:搭建区块链系统

在本机搭建一条分布式存储的4节点区块链系统,其网络端口要求如下:

机构名称 节点数 P2P端口 channel端口 rpc端口
机构A 1 30100 20100 8010
机构B 1 30200 20200 8020
机构C 2 30300 20300 8030

搭建完区块链系统后,需检查每个节点的连接数和运行状态。

根据题意,需要搭建 4节点 3机构 1群组

每一行的格式

ip:nodeNum agencyName groupList p2p_port,channel_port,jsonrpc_port". eg "127.0.0.1:4 agency1 1,2 30300,20200,8545

/root/tools 文件夹下创建 ipconf 并写入以下内容
127.0.0.1:1 agencyA 1 30100,20100,8010
127.0.0.1:1 agencyB 1 30200,20200,8020
127.0.0.1:2 agencyC 1 30300,20300,8030
使用 build_chain.sh脚本文件创建搭建,指定参数 -f为配置文件路径 -e为本地 fisco-bcos路径
bash build_chain.sh -f /root/tools/ipconf -e /root/tools/fisco-bcos

创建成功,会输出以下内容

检查节点运行状态

检查节点连接数
tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep connected

使用 tail 命令 查看 node0 的日志 并且使用grep进行日志筛选 ,connected 是连接日志的关键词 这里表示 node0与其他三个节点有连接

检查节点共识
tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep +++

也是 tail 命令 查看 node0 的日志 并且使用grep进行日志筛选 ,++ 是共识日志的关键词 这里表示 [g:1]它在 1 群组

子任务1-2-2:控制台配置与使用

启动控制台

切换到 root/tools/console目录下,并且把节点的SDK目录下的文件全部拷贝到 conf目录下

cd /root/tools/console
cp /root/tools/nodes/127.0.0.1/sdk/* ./conf/

进入 conf目录,拷贝 config-example.toml文件为 config.toml

cp config-example.toml config.toml

修改 config.toml配置文件

[network]
peers=["127.0.0.1:20200", "127.0.0.1:20201"]    # The peer list to connect

回到 root/tools/console目录启动控制台

bash start.sh

启动成功

子任务1-2-3:区块链系统权限分配

把三个账号分别设置为委员账号

先创建三个账号,使用 newAccount

newAccount
[group:1]> newAccount 
AccountPath: account/ecdsa/0x6eed2d6b063e71bb16086eb46c4425426d67b014.pem
Note: This operation does not create an account in the blockchain, but only creates a local account, and deploying a contract through this account will create an account in the blockchain
newAccount: 0x6eed2d6b063e71bb16086eb46c4425426d67b014
AccountType: ecdsa

[group:1]> newAccount 
AccountPath: account/ecdsa/0x3f2c7fa068b0a7b0ff1e0579c087eb3dd755c087.pem
Note: This operation does not create an account in the blockchain, but only creates a local account, and deploying a contract through this account will create an account in the blockchain
newAccount: 0x3f2c7fa068b0a7b0ff1e0579c087eb3dd755c087
AccountType: ecdsa

[group:1]> newAccount 
AccountPath: account/ecdsa/0x4ec1b4d20bfa3e1ea36f04756d82f2f879ad7b52.pem
Note: This operation does not create an account in the blockchain, but only creates a local account, and deploying a contract through this account will create an account in the blockchain
newAccount: 0x4ec1b4d20bfa3e1ea36f04756d82f2f879ad7b52
AccountType: ecdsa

先把设置 机构 A设置 委员账号,由于刚才启动控制台没有指定账户,现在是无名委员账号,可以直接指定委员账号

grantCommitteeMember 0x6eed2d6b063e71bb16086eb46c4425426d67b014
{
    "code":1,
    "msg":"Success"
}

现在 委员账号机构A,需要登录 机构A账户,使用 loadAccount 登录账户

loadAccount 0x6eed2d6b063e71bb16086eb46c4425426d67b014

再设置 机构B委员账号

grantCommitteeMember 0x3f2c7fa068b0a7b0ff1e0579c087eb3dd755c087

再设置 机构C委员账号的时候就需要委员投票大于50%才能设置成功,现在登录的是 机构A投票完,再登录 机构B账号进行投票

grantCommitteeMember  0x4ec1b4d20bfa3e1ea36f04756d82f2f879ad7b52
loadAccount 0x3f2c7fa068b0a7b0ff1e0579c087eb3dd755c087
grantCommitteeMember  0x4ec1b4d20bfa3e1ea36f04756d82f2f879ad7b52

返回 code是 1 设置成功

{
    "code":1,
    "msg":"Success"
}
设置机构 A 账号的投票权重为2

现在登录的账号是 机构B,设置为需要登录 机构C,投票一下

updateCommitteeMemberWeight 0x6eed2d6b063e71bb16086eb46c4425426d67b014 2
loadAccount 0x4ec1b4d20bfa3e1ea36f04756d82f2f879ad7b52
updateCommitteeMemberWeight 0x6eed2d6b063e71bb16086eb46c4425426d67b014 2

查询投票权重为2

queryCommitteeMemberWeight 0x6eed2d6b063e71bb16086eb46c4425426d67b014
Account: 0x6eed2d6b063e71bb16086eb46c4425426d67b014 Weight: 2
